ARTICLE OF PAPER OR THE LIKE.

Specification of Letters Patent.

Patented Sept. 5, 1216.,

To all whom it may concern Be it known that 1, WILLIAM H. JAooBs, a citizen of the United States, residing at New York, borough of, Manhattan, county and State of New York, have invented certain new and useful Improvements in Articles of Paper or the like, of which the following is a clear, full, and exact description.

This invention relates to improvements in articles made of paper or similar material, and more particularly relates to an improved envelop, bag or mailing wrapper.

One of the objects of the invention is to provide means for reinforcing the edge of the pocket opening of such articles.

Another object is to provide an article of the class mentioned which can be made in an ordinary paper bag machine from a straight sheet without any extensions laterally of said sheet which are necessitated by the usual construction of the pocket ends of such articles.

Further objects of the invention are to provide a simple, practical and efficient article of the class mentioned.

These being among the objects of the present invention, the same consists of certain features of construction and combinations of parts as applied to the article and the blank from which the article is made, to be hereinafter described and then claimed with reference to the accompanying drawings illustrating suitable embodiments of the invention, and in which drawings Figure 1 is a plan view of a bag suitable to be made under the present invention; Fig. 2 is a perspective view of a bag incised in accordance with the present invention; Fig. 3 is a plan view of the bag shown in Fig. 2 on which is indicated an applied piece of reinforcing material and paste for the bag; Fig. 4: is a fragmentary view of the parts shown in Fig. 3 in which the turned-under part for the pocket is shown as pasted down; I

Fig. 5 is a view similar to Fig. 4: in which the transverse portion of the pocket is shown as pasted down together with its lateral wings or ears, to form a complete article; Fig. 6 is an enlarged transverse section on the line 66 Fig. 5; Fig. 7 is a section on the line 77 Fig. 6; and Fig. 8 is a view of a modification, in which the invention is shown as applied to a mailing wrapper.

Referring to Fig. 1, a flattened tube 10 is shown which may be made in an ordinary bag machine and is composed of paper or other suitable material. The bottom 10 of the bag may be closed before the other end of the bag is formed, in accordance with the present invention. Preferably while the tube 10 is on a former of the machine, the side edges of the same are slitted longitudinally for a suitable distance at 11, 12, so as to provide a portion llextending from the body of the tube or bag and a flap 13, as shown in Fig. 2. Either simultaneously with or after the slitting of the bag or tube at 11, 12, slits 15, 16, are produced in the extended body portion 14, which slits are parallel with each other and with the slits formed at 11, 12, said slits 15, 16, being located nearer to the free side edges of the face of the body portion 14:- than they are to each other. Inasmuch as the described slits extend longitudinally of the body of the bag or tube, the same may be conveniently formed in most any bag machine, although the invention is not limited to producing the article in a bag machine. As shown in Fig. 2, there will be provided by reason of the described incisions, a transverse portion 17 at the ends of which are lateral wings or ears 18, 19, between which is located a portion 20 which is joined to the portion 17 along the dotted line indicated. The so slitted bag or tube will be seen to constitute a blank as it were, for the complete bag or envelop. Preferably while the said slits are being formed, the slitting knives are prevented from injuring or cutting the flap 13. The latter may, however, be afterward formed into any desired shape, as for instance the corners thereof may be cut off.-

The described blank is now ready to be formed up so as to produce an article with a pocket into which the fold-over'flap 13 may be inserted. Referring to Fig. 3, it will be seen that a strip 21 of tape, cord or string, or other suitable flexible material is stretched transversely across the blank along that part of the transverse portion 17 to which the part 20 is attached, and the same is introduced for providing a reinforce in the complete article. Preferably the ends of the said reinforce are extended beyond the slits 15 and 16 and toward the outer ends of the lateral wings or ears 18, 19. Paste is now applied as at 24, or the paste may first be applied and the reinforce 21 applied afterward. It is desirable, although not abso- -lutely necessary, that a reinforce be applied.

- pasted down upon the same surface of the body along the edge portions at 26, 27. Obviously the corners of the flap 13 may be turned over as indicated in dotted lines. The article being now complete, it will be seen to have a pocket at 28, as more clearly shown in Figs. 6 and 7. This pocket ex- .tends transversely of the body and is adapted to be engaged by the fold-over flap .13. It will be seen that the material which has been cut out from between the wings or ears 18, 19, is made use of in the pocket, as it constitutes a turned-under part which provides a folded edge for the pocket opening, andat the same time incloses the reinforce 21. The lateral wings or extensions 18, 19 from the transverse portion 17 and hence from the pocket 28, are made use of to stiffen and strengthen the pocket end of the article. If a reinforce is used such as described, the yvings are made use of to anchor the ends 22, 23 of the reinforce, which ends in the complete article extend to one side of the edge of the pocket opening and laterally away from the pocket. It will be noticed that by extending the ends 22, 23 of the reinforce in the direction shown, the edge of the pocket opening'is better able to. withstand any strain which is imposed in the direction of the closing flap when it is engaged with the pocket.

Fig. 8 illustrates a modification in whic the invention is shown as applied to a mailing wrapper, which may consist of a body 30, with or without lateral extensions 30. One end 31 of said body as indicated in dotted lines, is provided between its free edges with parallel slits 32, 33, which correspond in function to the slits 15, 16 before mentioned. In the same way as before, a pocket will be formed at the corresponding end of the body 30, so that the latter has a transverse portion 34, a turned-under part 35, and wings 36, 37 extending laterally from the transverse portion 34.. A reinforce is not here shown. At the opposite end of the body 30 it is provided with a flap 38 which, when the described wrapper is wrapped around an object, is brought over the transverse strip 34 and engaged in the pocket.

It will be seen that under the present invention a straight strip or tube may be used,

to be cut, folded and pasted so as to produce an article with a pocket to be engaged with a closing flap, and that unless desired, the body of the article, if it be a bag or envelop, need not be out or slit at all. It will furthermore be seen that in the preferred form of the invention there are no lateral extensions necessarily from the tubular body, either in the process of manufacturing the article or when the article is complete.

Any feature of the present invention which is disclosed herein and not claimed and which relates to the wrapper such as disclosed in Fig. 8, is reserved for a subsequent application.

Obviously the invention is susceptible of further modification, as parts may be omitted, parts added, and parts substituted without departing from the scope of the inven tion as expressed in the claims.
